Newly designed surface high-performance matrix to boost Li-S battery performance (IMAGE)
Caption
Single-crystal CoSe2 can exhibit three types of terminated (011) facet, efficiently obtaining the surface with a high-rich Co3+-Se bond termination, in contrast with lots of surface grain boundaries and dangling bonds in polycrystalline CoSe2. As anticipated, it can provide high-density and high-efficient active sites, enormously suppressing the shuttle effect and improving the reaction kinetics via accelerating the conversion and deposition of polysulfides and Li2S during long-term charge/discharge process.
